The OSC-Springfield offices would officially open in April 2004. Over the next several months, OSC engineers would install the 16-MSP Cray X1 system, the Cray XD1 system and the 33-node Apple Xserve G5 Cluster at Springfield office. A 1-Gbit/s Ethernet WAN service linked the cluster to OSC’s remote-site hosts in Columbus. The G5 Cluster featured one front-end node configured with four gigabytes of RAM, two 2.0 gigahertz PowerPC G5 processors, 2-Gigabit Fibre Channel interfaces, approximately 750 gigabytes of local disk and about 12 terabytes of Fibre Channel attached storage.

In September, 2003, OSC engineers installed a SGI Altix 3700 system to replace its SGI Origin 2000 system and to augment its HP Itanium 2 Cluster. The Altix was a non-uniform memory access system with 32 Itanium processors and 64 gigabytes of memory. The Altix featured Itanium 2 processors and runs the Linux operating system. OSC's HP Cluster also included Itanium 2 processors and runs Linux.
